Discover the magic of a night sky hike, when even the most familiar trails reveal sights and sounds they only share with the cool, quiet night. Explore this mountainous landscape as we navigate the Green Mountain trails under the evening skies. This hike is perfect for anyone - no prior hiking experience required - though you'll need to feel comfortable walking in the dark over uneven terrain for about 3 miles. You bring the hiking boots, we'll bring the headlamps!

  • Hike one of our favorite trails under the cover of the night sky
  • Learn tips and tricks for navigating the darkness
  • Headlamps provided
